Well...both lol. Idk it seems decent. Couldn't completely tear it down I didn't have the 10" extension to get to the main bolt holding the upper on. Looks like it would be a hell of a lot of fun for under $500. Shoots 2 3/4 and 3".

Well we ran about 100 rounds through the mka in about 20 minutes. It handled slugs,buck,bird and steel no problem. We had 1 fail to feed at the end. Very accurate and ridiculously fast and reliable. This gun is a must have. Wish I could post the video of the boss bump firing it. Lmfao.
